T0 all whom it may concern.: 'j Be it known that I, 'BURR CUSTER, a citizenv of the United States, and.. resident of yMarion., inthev county of Grantfand State, of Indiana, have invented'cert'a-Fin new and .useful Improvements in Weldiiig-Torche,s;4

and do hereby declare the following to be a full, clear, and exact description of the invention, lsuch as will enable others skilled in the art to which it apperta-ins to makev and use the same. l

This iivention relates to improvements 'in welding torches,the object yof the invention1 being to provide a device-of this 4 character in which the gas and oxygen shall be thoroughly diffused and mixed before vreaching the jet or flame orifice, -and in which the size or extent of the Haine may bey i readily and accurately controlled.

` claims.

embodiment of my invention. view at right angles to Figpl. Figs. 3 and' L1 are top and bottom plan .views of the noz` With this object in view the invention consists in certain novel'feature of construction and'combinations of 'parts as hereinafterv described and In the accompanying drawings, Figure 1 is a View, partly in section, illustrating an Fig. 2 is a zle 37; Fig. 5 is an enlarged end view of the block 13; Figs. 6 and are enlarged transverse sectional views of the block 13, and Fig. S'is an enlarged longitudinal sectional view of said block.

1 represents a cylinder which'. constitutes the tubular handle portion of `the implement and forms a chamber 2. A plug 3 is located n fone end of the cylinder 1 and this end is closed by a cap fi. A pipe' 5 passes through the cap l and plug 3 and at its inner end discharges into the chamber 2 of the cylinder,-tlie outer end of said pipe being provided with a valve 6 and the" casing of this 1valve is provided with a shank`7 to receive a rubber hose 8 by which acetylene. or other gas is conveyed tothe chamber 2 of the cylinder. A pipe 9 also passes through the plug 3 and cap /l and this pipe is provided with a valve 10, the casing of which is constructed with a shank foi` the reception of a hose 11 by. means of which oxygen is conveyed to the implement.

The pipe 9 extends through the chamber 2 of the cylinder 1 .and'at'its forward end communicates with Va chamber 12 located pointed out in the,

lsmall ducts 35.

der-1 near itsl forwardI end. A: plug 14;

i's\'lo"cated in the forward end of .they cylinder and may be retained Iin' place by acap 15. The plug 14 isina'de with a conical recess which, with the space between the plugs 13 and 14 forms a chamber 16.

rEhe plugl is provided with a plurality'of longitudinal ducts 17 .and communicating ,transverseducts 18, the. forme-r communicating'with the chamber 2 of the cylinder and the transverse lducts' communicate with small jet orifices 19 which."dis charge into..

.the chamber 16.' The plug 13 is also :pro-

vided with a plurality of communicating ducts 2O which also communicateywith the.

the gas will be thoroughly diffused and the oxygen will lbe also diffused by' its passage through thejducts 20. and-'both the gas and i the oxygementeringthe chamber 16-through numerous small jet orifices 21I will become thoroughly mixed in said chamber 16. The

mixed 'gas and oxygen will leave the cham-'f ber. 16 through a pipe 22 (which is preferably curved) and the. forward end 'of this pipe communicates with a nipple 23 on the tubular head 24 of the implement.

y The nipple 23 is so disposed with relation to the head 2land the pipe 22 that said head will be in a diagonal vposition ywhen the tubularhandle portion or cylinder is ina horizontal position.

The upper end ofthe tubular head 24 is closed, as at 25, and 'provided with a threaded flange 26 to receive a cap 27. A rod 28 passes through the cap 27 and the endv 25 of thehead and 'the space between said end 25 and ca'p 27. forms a compartment in Which packing 29 for said rod is located.

' The upper end of .the rod is provided with la hand wheel 30 and between said hand wheel and the cap 27, a spring 31 is located. Near the l'ower endv of the'tubulai' head `24,

a diskA or partition'32 is located and the space betweenl said disk or partition and the end 33 of the head 24,. formsa chamber 34 which' communicates with the interior of the tubular head bymeans of a plurality of The lower end 33 of the head 24 is provided with a duct 36 for a purpose presently explained.

'The rod 28 passes. through the partition sofl 32 and alsothroughhthe end 33 of the head '24-and enters a c onical nozzle 3T to which it `is secured.V This nozzle is providedl with -ay plurality of ducts 38 which diiier from each. other in 4size and therefore in capacity-- and,Y the lower end vof each of said ducts vdischarges at the apex of the conical nozzle.

jWith the parts in lthe position shown in F 1g. l, .the mixed gas-and oxygen from'the chamber 16 will 'pass through the pipe andenter the tubular head '24., from which lao .at hand', may be provided.

SaidA mixture lWill pass `through the small ducts 35 and through the chamber 3i to the largest of the jet ducts 38 and Will be burned at the 'apex of the conical nozzle, aiording the largest iame of Whichthe device is capable.. By rotating'the conical nozzle 37 (on its bearing 39 at the lower end of the head 2i) by means of the rod 28, one of' thev 4Smaller jet ducts 38 maybe brought into communication with the outletduct 36 and .thus a smaller.V flame, according to the needs Having fully described 'my invention what l claim as new, and desire 1. In a Weldingv torch, the combinatie With a tubular handle portion provided therein with gas and oxygen diti'usingmeans and a mixing chamber, of a head communieating with said mixing chamber, a revolui ble jetV cone attached to the lower endofsaid head and provided ivith a plurality of jet ducts differing in size, and means for turning said cone to bring any-of said jet ducts into communication with said head.

2. Ina welding.torch,' the combination with; a tulol'ilar handle portion, means -or discharging gas thereinto, a diffusing device vvithin said tubular handle and communicating With theinterior thereof, a pipe for oxygen communicating with said diffusing device, and a mixing chamber communicating with said diffusing device, of a tubular head, a pipe connecting said tubular head withthe mixing chamber of the tubular hanvdle, an adjustable jet cone attached to theloWer end of said tubular head and `having a plurality of jet duct-s diiering in size, andmeansl for adjusting'said cone to bring any to secure by. Letters-,Patent is: v v

one of said jet ducts into communication with the interior of the head.

3. In a Welding torch, the combination with a tubular head and means -for discharging mixed gasand oxygen thereinto, said head'having a single duct at one end, ofa revoluble 'jet cone attached to said head and provided With a plurality of jet ducts differing in size, and means for turning said cone to bring any one of said jet ducts into communication with4 the duct in the end ot said head, saidpjet cone having a plurality of jet ducts different in capacity.

5. Ina Welding torch,the combination of a tubular handle portion provided with a 'mixing chamber, a. diiiusing device in said handle adjacent to the mixing chamber and comprising a block having tivo sets of transverse ducts, said block also having longitudinal ducts vconnecting. one. set of transverse ducts with the interior of the handle andl saidl block having another set ofI longitudif nal duets connecting ythe same transverse ducts with themixingchamber, means for discharging gas into said handle, a pipe for conveying oxygen to the'other set of transverse ducts in the block, and said block having longitudinal ducts connecting the last-mentioned transverse ducts with 'the mi'xingchamben and a .torch head connected with the mixing chamber.

In testimony whereof, I have signed this speciication in the presence of two subscribing Witnesses. y
